PIC18F87K22 FAMILY
In addition to the expanded range of modes available
through the CCPxCON and ECCPxAS registers, the
ECCP modules have two additional registers associated
with Enhanced PWM operation and auto-shutdown
features. They are:
• ECCPxDEL – Enhanced PWM Control
• PSTRxCON – Pulse Steering Control
